High Pressure Coolant Injection (HPCI) System Risk-Based Inspection Guide. Pilgrim Nuclear Power Station

摘要

A review of the operating experience for the High Pressure Coolant Injection (HPCI) system at the Pilgrim Nuclear Power Station is described in the report. The information for the review was obtained from Pilgrim Licensee Event Reports (LERs) that were generated between 1980 and 1989. These LERs have been categorized into 23 failure modes that have been prioritized based on probabilistic risk assessment considerations. In addition, the results of the Pilgrim operating experience review have been compared with the results of a similar, industry wide operating experience review. The comparison provides an indication of areas in the Pilgrim HPCI system that should be given increased attention in the prioritization of inspection resources.
